ACCIDENT AND OPERATING EXPERIENCE AT INTERCHANGES

GEOMETRIC HIGHWAY DESIGN CAN BE EVALUATED ONLY IF THE RELATIVE MERITS OF THE DESIGN FEATURES CAN BE MEASURED IN SOME FASHION. A YARDSTICK IS NEEDED THAT WILL MEASURE THE VARIOUS DESIGN FEATURES. STUDIES HAVE BEEN UNDER WAY FOR THE PAST TWO YEARS TO EVALUATE INTERCHANGES BY THREE MEANS- ACCIDENT RECORDS, OPERATION, AND CAPACITY. INTERCHANGES CAN BE BROKEN DOWN INTO THREE BASIC ELEMENTS: (1) THE EXIT TERMINAL, (2) THE MAIN PORTION OF THE RAMP, AND (3) THE ENTRANCE TERMINAL. THIS PAPER ATTEMPTS TO SHOW HOW A VARIATION IN THE DESIGN OF THESE BASIC ELEMENTS AFFECTS OPERATION AND SAFETY. /AUTHOR/
